TITLE: Absorption of cyclotron oscillations in a heterogeneous

TEXT: Apparatus and results of measurement are described for the
absorp-
tion of high-frequency energy in a h drogen plasma produced in a quartz
tube (5.5 cm diameter, 100 cm lengZlby a Penning discharge. Capacitor
2 microfarads, charged to 5 kv, maximum discharge time did not exceed a
few microseconds. The plasma was under the action of a longitudinal
mag-
netic field, also produced by a capacitor discharge to a solenoid
(18 milliseconds quasisteady, 104 - 1.6-1o4 gauss). Measurements were
made
in the time interval of 300 - 1,000 mforoseconds after ignition of the
plasma discharge. The plasma oscillations were excited by a 10.7 Mcps,
300-w coil (axial period A - 11 cm) as described by G. N. Stix (Phys.

Fig. 1
shows the results of measurement: dependence of the high-frequency
power
absorbed in the plasma on the magnetic field strength at various
moments
after discharge ignition, i.e., at different ion densities (hydrogen
pressure 6-10- 3 mm Hg). The authors interpret the course of the
curve -,r
stating that the cyclotron oscillations with high densities are
excited in
the peripheral plasma layer and, moving to the axis, meet a layer
with
critical ion density, where they are absorbed. Fig. 2 shows this
dependence'for 1.3-10- 3 mm Hg; herep the ion density in the
discharge is
considerably lower, and cyclotron oscillations can be excited in the
region
of H = H0 only. In all experiments, the ion temperature in the plasma
hardly exceeded 1 ev. Under such conditions the cyclotron damping
with
H values where absorption obours, is no'longer important cf. R. Z.
Sagdeyev,
V. D. Shafranov (Fiziks plazmy i problems, upravlyayemykh
termoyadernykh
reaktsiy, 11, 430, 1958)- But the absorption caused by collisions
between
unequal particles should still be very considerable. The authors

ABSTRACT: The effect of a high-frequoncy azimuthal electric field
on.the decay rats
of hydrogen plasmas in a magnetic field was investigated
experimentally. V.V.Dolgo-:
polov, IC.N.Stepanov and the present authors have described the
apparatus in detail
elsewl'icre (ZhTF 34,No.6,1064)'. The plasmas viere produced in a
G cm diameter glass
tube by a Penning discharge between cathodes separated by 800 cm.
Thirty microseccads
after the discharge, the plasma tom crature had dropped below I 6V
but the charged
particle density was still 1.7 x 10?3 cm73. The subsequent rate of
decay of the
plasma was independent of the strength of the longitudinal
magnetic field provided
this was not less than 1.5 kOo. This is ascribed to predominance
ig the decay mech-
anism of recombination over diffusion to the walls. A 7.45 tic

longitudinal electric lield'component was applied to the decaying
plasma by means
of a section of an artificial holical LC lino. Whon this
high-frequency field was
sufficiently strong, its application increased the decay rate of
the plasma at all
values of the static longitudinal magnetic field strength; the
increase was parti-
cularly marked, however, at a magnetic field strength of 5.6 k0e,
at which the ion
Larmor frequency is some 15% greater than the frequency of the
applied field. Weak
high-frequency fields were found to decrease the plasma decay rate,
but the decay
rate was increased by fields exapedihU a certain critical amplitude
that increased
with increasing pressure. The decrease of the decay rate in weak
high-irequency
fields is ascribed to heating of the plasma, and the increase in
strong fields to
enhancement of the plasma diffusion rate. The diffusion
ordiancomont mechanism is
not understood, but it is suggested that a drift instability due to
nonuniform heat-
in- may be involved. The authors briefly discuss the effect of the
observed phone-
mena on heating of plasmas at the ion cyclotron resonance under
such conditions that
the longitudinal electric field component is significant. 'Ve
tender~our gratitude
